Usage and function

1. Due to the special activity of the silicon-halogen bond, a series of organosilicon compounds containing silicon-functional group structures can be synthesized, such as trimethylalkoxysilane, hexamethyldisiloxane, and hexamethyldisilazane. .

2. It can be used as a protective group for functional groups such as hydroxyl, carboxyl, amino and other functional groups. The reaction of attaching and removing trimethylsilyl groups has high yield, mild conditions and wide application range, and has been widely used in organic synthesis.

3. Some biochemical samples are reacted with trimethylchlorosilane to obtain silanized derivatives, which have high volatility, which enables the gas chromatographic analysis of biochemical samples.

4. Trimethylchlorosilane is used as a capping agent for organosilicon polymers, which can regulate the molecular weight of polymers, and is especially widely used in the production of silicone oils.
